Peter Altschul demonstrates the use of his BrailleNote

Peter Altschul, an organizational psychologist, demonstrates how he used his BrailleNote to write his memoir "Breaking Barriers: Working and Loving While Blind" on Oct. 8. He started writing the book in 2007 and finished on Labor Day weekend in 2011. The book chronicles a two-year period in his life, beginning when he acquired his fifth guide dog, a Labrador named Jules and ending with his move from Washington, D.C., to Columbia.
